package main

import (

    "net/http"

    // 1. you can using default handler in profile defined

func registerHandler() {
    profile.HandleFunc("GET","/myself/controller", func(ctx *rpc.Context) {
        // todo something
    }, rpc.ServerOption...)
}

func main() {
 	ph := profile.NewProfileHandler("127.0.0.1:8888")
		httpServer := &http.Server{
			Addr:    "127.0.0.1:8888",
			Handler: rpc.MiddlewareHandlerWith(rpc.DefaultRouter, ph),
		}
		log.Info("Server is running at", "127.0.0.1:8888")
